SHACKLE.

SPEGIFIGATIONforming part of Letters Patent No. 787,430, dated April 18,1905.

Application filed May 24, 1904. Serial No. 209,469.

To all whom it may concern.-

the wrists and ankles and gives the prisoner' a limited amount offreedom for a predetermined length of time and at the end of said timethe said freedom is taken up and the same cannot be released only by akey, and

the predetermined time of freedom may be readily varied, as desired.

Another object of our invention is to provide a shackle of thischaracterwhich is supported upon the shoulders of the wearer and which is adaptedto be secured therein so that the same cannot be removed, and carried bythis are the Wrist and ankle attaching members.

A still further object of our invention is to provide a more simgle,cheap, and eifective shackle of this character and one that may bereadily attached to any one. a

In the accompanying drawings, Figure 1 is a perspective view showing ourdevice applied. Fig. 2 is atop plan view of the device removed. Fig. 3is an enlarged sectional view of the trigger forholding the plungeroutward. Fig. 4: is an enlarged vertical sectional view taken on line mmof Fig. 2. Fig. 5 is a side elevation of the complete device. Fig. 6 isan enlarged vertical sectional view taken on line ;1 1 of Fig. 2. Fig. 7is an enlarged sectional view of the chain holding and locking means.

Referring now to the drawings, 1 represents a steel tube, which, asshown, is of a semicircularshape to fit over the shoulders of thewearer, and secured to said tube 1 isa 5 secondtube 2', which is of ashape precisely 2 of the drawingsthat is, side by side.

that of the tube 1, and the two tubes are secured together in a positionas shown in Fig. It will also be seen that there are two sets of tubes 1and 2, as clearly shown in Fig.1, and are connected at the rear with ametal frame 3, in which is mounted the clock mechanism, which will behereinafter more fully described. The said tubes adjacent their lowerends are provided with a belt 4:, by means of which the same is securedaround the waist, and the tubes are also provided with loops 5, throughwhich the arms pass, and thus the device may be readily secured to theprisoner. The said tube is further connected by a strap 6, which passesover the breast, corresponding with the metal frame 3, which passesacross the back.

The tubes 1 and 2, as before described, are precisely alike, while thetube 1 carriesacoilspring 7 in its front lower end and the tube 2carries a coil-spring 8 in its lower rear end, as clearly shown in Fig.2. The said springs bear against the outer ends of the tubes, and saidtubes are provided with openings 9, through which the chain 10 passes,and said chain passes through said coil-springs and is provided withplungers 11, which bear against the ends of the coil-springs. Theseplungers are adapted to bear against the springs and form means wherebythe said springs are held in their compressed positions, as shown inFig. 2 of the drawings, while Fig. 3 of the drawings shows the springsreleased and the chains drawn inward. The outer ends of the chains 10are provided with gyves, which are. of any ordinary form, provided thereis a locking means for firmly holding the same closed,and they can onlybe released by a key, thus absolutely preventing the same from beingtaken off or opened.

% The lower ends of the tubes 1 and 2 are each provided with a housing12,- in which, as clearly shown in Fig. 5, is the chain-lockingmechanism, which we will now proceed to describe. The said housing 12 isprovided with a central opening 13, through which the chain 10 passes,and pivoted to-the lower end of the said housing are the two pawlmembers 14 and 15 and between which the chain is adapted to pass. Thesaid pawl members 14 and 15 are provided with springs 16 and 17, whichbear against the pawls and normally hold the same in engagement with thechain, and thus it will be readily seen that the chain can readilytravel inward; but any outward strain on the chain causes the pawl tolock more firmly, and thus it is impossible to pull the chain out of thetubing. In order to allow the prisoner the freedom desired, we providethe pawls 14 and 15 with a locking mechanism 18, whereby the said pawlsmay be drawn outwardly out of engagementwith the chain and the sameallowed to pass out from the tube, thus giving a greater movement to thearms or legs of the prisoner wearing our shackle. The saidlockingmechanism 18 may be of any desired form, but preferably of theYale night-latch style, and the outer end of the latch proper isconnected to the pawls, and thus it will be seen that said pawls cannotbe moved to release the shackles until the latches are released, whichare operated by a key. By this structure it will be impossible to pullthe chain from out of the tube until thelatches are moved or released,which draws the pawls away from the chains and allows the same to bepulled outward, thus compressing the springs carried by the tubes. Inorder to hold the said springs in their compressed positions, so thatthe chain may remain outward, giving a limited freedom to the prisoner,we provide a pivoted latch 19, which is pivoted Within the adjoiningtubes at 20 and has an outwardly-extendingportion 21, which passesthrough an opening 22 in the tube and against which the plunger 11 isadapted to bear, thus holding the spring compressed. In order tonormally hold said latches 19 in an inward position, We provide springs23, which bear against said latches, as clearly shown in Figs. 2 and 3.The outer ends of said latches are provided with eyes 24:, to which aresecured a rope or cord 25, which extends inwardly and is operativelyconnected to the clock-opening mechanism 26, which is carried within themetal casing 3, thus preventing the same from being tampered with and atthe same time providing a means for connecting the two series of tubeswhich forms our improved shackle. The clock mechanism is set for anydesired time, and at the said time the clock mechanism starts a windingmechanism 27, which causes the cords 25 to be drawn inward, which drawsthe latches 19 inward, releasing the springs, and draws the chainsinward, thus taking up the chain and relieving the prisoner of thelimited amount of freedom. After the said chains have been drawn inwardit will be impossible to draw the same outward, as heretofore described,and the hands and feet of the prisoner are firmly held. Thismechanism,as clearly shown, simply operates the latches at the rear ofthose which are adapted to control the movement of the legs.

The front-latch-operating mechanism for releasing the springs iscontrolled by cables 28, which pass over pulleys 29 and are connected tothe eyes in the latches 19. The said cables passing through the tubehave their ends connected to a pivoted lever 30, which is mounted underthe end of the latches of the front of the shackle, and as the cablesare drawn by the winding mechanism the lever 30 throws the latches 19outward, thus simultaneously releasing the springs at both front andrear.

Our device is adapted more particularly for shackles used in thetransportation of prisoners, in which they are allowed a limited amountof freedom by the length of the chains carrying the gyves, and the clockmechanism can be set so that at such and such a time the same willrelease the springs, and thus take up the chain and relieve the prisonerof their freedom, and the chain cannot be pulled from the tube by mainforce of the arms or legs of the wearer, owing to the pawl arrangementheretofore described.
